Harry Potter Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

LEGO is the best-performing harry potter brand in July 2026, moving 7,000 units across 3 ASINs for 37.2% of Top 10 volume. Betty Crocker follows with 3,000 units (16.0%), ahead of Harry Potter on 2,800 units (14.9%).

With 7 brands splitting the Top 10 and 68.1% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $4.97 to $54.38, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B07WQY5HWP booked 800 units at $19.89, with ▲ 14.3% MoM change. On the growth side, B0CRFZ5PZQ leads positive momentum with ▲ 100.0% MoM growth on 2K units, with B0CS7VH7HM close behind at ▲ 100.0% MoM on 2K units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
